Rb20Det Coil Pack Cover

[rayj]

Hi,

I know this question has been asked before, and most people just leave the cover off to increase ventilation.

Is ventilation in this area really that important important though? If it was, wouldn't the engineers at Nissan add some ventilation features into the cover's design?

I'm assuming coil packs are made to withstand very high temps, and as such do not require high ventilation, unless of course you have a very high powered car...

My car for example is a lightly modded car, running at about 11-13psi.

At the moment my cover is cut, and only the section where the ignitor mounts is left.

I have a complete one, and was thinking of cutting it in half under the cross over pipe for easy removal.

Any opinions/facts?

Thanks

im not sure, but i think the problem is to do with the age of the coilpacks.. new coil packs will be fine as the plastic is still soft.. but over years of use and high temps the plactic starts the break down... so if youve got new coilpacks i couldent see why they wouldent last another 10 or so years? personally i keep my cover on.

If you use it on track you may as well take it off. I dont think it would make a difference daily driving.

yeh i was thinking the same thing... after so many years the coil packs start to degrade and get affected adversely by heat

im gonna keep the cover on and cut it in half with a space of 10mm or so. that will offer some form of ventilation and easy removal.

dont bother cutting it dude either run it or run without it.

cover on - no water and dirt cant get in that area, less chance of getting defected

cover off - coilpacks will last longer

so its personal preference, i never ran one

And if you do get crap in there, there's more chance you'll get missfire due to coil to head arcing.
